Awhile back I encoded all of my DVD's and put them on a NAS (Synology DS411). Recently we've purchased 2 "Smart" TV's, both of which have the ability to access a DLNA server. I'm seeing 2 different symptoms with my videos on the 2 TV's. I'll list the TV's and the issues i'm seeing.
All videos were encoded using Handbrake with the "Apple TV" or "Apple TV 2" profiles.
TV 1: Panasonic VIERA TC-L42E50
Nearly every video will get to a point and then just stop playing. If I re-encode the video using handbrake "Normal" profile, and be sure to change the audio source from "aac (ffmpg)" to "aac (faac)" then I can get a copy of the video that plays fine on the tv, but I had to re-encode and loose all of the video quality.. plus we're talking a lot of video files.
TV 2: Samsung UN60F7100
This TV can play the same files the Panasonic crashes trying to play, but seems to get out of Sync the further into the video you play. In the course of a 1.5 hour movie the A/V sync is horrible at the end. Once again, re-encoding the video solves the problem using handbrake "Normal" profile, and be sure to change the audio source from "aac (ffmpg)" to "aac (faac)".
Other interesting info: I have a Boxee box at home and the Video file plays perfectly on it, as well as plays perfectly on the PC
So my first question is... is this a problem with the TV, the DLNA server, or the Video files.
1) The fact that both TV's have some issue with the files leads me to believe that the Software playing the files on the TV's just isn't as good as the software in the Boxee box and whatever is wrong, it's just not sophisticated enough to deal with it... It's unlikely I'll get a fix from either TV manufacturer.
2) I tried playing the video on the Samsung tv by playing it off of a USB thumb drive, the video was still out of sync by the end of the movie, but possibly not as out of sync.. but that probably rules out the DLNA server.
3) The video file - This must be at least most of the problem.. considering that a re-encode solves it. Now I just need to figure out what's wrong with the video file/what part of the encode it is that these TV's don't like. I THINK it might be the audio encoding that's messed up.. but that's just a hunch.
Does anyone have advice as to the best way to analyze the video file to try to hunt down the root of the issue? Once I figure that out I need to figure out the quickest/least destructive way to repair the files.
Thanks for your help!
